——————aids had left a scar on Ajani and his sister ,their grandfather's face turned
white.
a when he heard b having heard c when hearing d on hearing

答案

答案是A
B,C和D在逻辑上都是错误的,因为face这个主语是不能hear什么的.只有从句（when he heard ------,their grandfather's face turned white）才能弥补这样的逻辑错误.
又如：When the boys were playing baketball,their girl-friends were watching them.(这句是对的),但如果变成了-----Playing baketball,their girl-friends were watching them,条理就乱了：到底是谁在playing basketball?你的句子也就是这样的条理问题.
